Easy filter on key's would be sick

Keep a local history

It would be cool if I could come back to json.pub and look at past data I’ve inspected. This could be especially useful when referencing large objects that I work with on a regular basis but don’t fully “hold in my head”

Collapse/expand all

For long lists, would be nice to collapse/expand all!

Switch sides

Can we add a button to switch the content from left to right and vice versa? The use case is this: when you paste unformatted JSON on the left, the formatted JSON appears on the right. However, I’d like to edit the formatted JSON directly. By switching the formatted JSON to the left and the original text to the right, it would be much easier to make adjustments.
